Description

SEALED POT DISTRIBUTOR OF A SOLID OR PASTY PRODUCT DOMAINE DE

THE INVENTION

  The invention relates to the field of dispensers for cosmetic products and typically cosmetic products with solid or pasty consistency, for example creams.

  These cosmetic products are usually distributed in pots.

STATE OF THE ART

  Conventional pots are known which comprise a body forming a cavity for containing said cosmetic product with an upper opening adapted to be closed by a sealing means.

  Generally, the sealing means is a cover or cap adapted to be screwed to said body.

PROBLEMS POSED

  On the one hand, traditional screw-top jars need to be grasped in both hands to open and close them, which has disadvantages in handling and ergonomics.

  In addition, the lid once unscrewed must be placed next to the pot, with the disadvantage of taking up space and the risk of seeing it go astray.

  On the other hand, it is necessary to renew the packaging of cosmetic products, especially when the products themselves are renewed, in order to solicit the attention of the users of said cosmetic products and thus promote the act of purchase.

  In addition, the formulations of cosmetics are constantly evolving and as certain cosmetic compositions comprising at least one volatile constituent are emerging, it is important to have a sealed dispenser adapted to these new formulations. Finally, there is a need to have distributors adapted to the bathroom, that is to say distributors placed on a plane and easy to use directly, and for example easy to open.

DESCRIPTION OF THE INVENTION

  According to the invention, the pot intended to contain a pasty or solid product, typically a cosmetic product, comprises a body comprising a cavity provided with an upper opening and capable of containing said product, and a lid for closing said upper opening, said lid and said body being secured by a hinge formed by cooperation of a first hinge member integral with said body with a second hinge element integral with said lid.

  This pot is characterized in that: a) said pot comprises a closure means operable by manual pressure, typically by axial pressure, said closure means comprising an upper closure element integral with said lid cooperating with a lower integral closure element of said body so as to lock / unlock the lid manually with respect to said body, b) said lid comprises a seal, made of an elastic return material, adapted to cooperate with said upper opening when said lid is closed, c) said upper opening is surrounded by an upper flange for cooperating with said seal when said pot is closed, so that said seal is compressed, sealingly, between said upper flange and said cover when said pot is closed.

  The pot according to the invention solves the problems posed.

  Indeed, this pot can be opened simply by a simple manual pressure, and typically by axial pressure, so that this is a pot whose use can be described as ergonomic and which is just as easy to close, since it is sufficient to rotate the lid around its hinge.

  In addition, since the cover is integral with the body through the mechanical connection hinge, there is no risk of losing it while applying to the body the contents of said pot.

  This pot, thanks in particular to its closing means operable by manual pressure, and typically by axial pressure, is radically different from existing pots and allows to renew the packaging of cosmetics, which is of great importance on the commercial plan.

  Finally, by its design, this pot can ensure a conservation and use of product formulations comprising a volatile component, which can also allow the packaging of new formulations.
